“When they look at the documents, I think people are going to see a lot of bad things happened. I hope it’s not so, because if it is, there’s never been anything like it in the history of our country,” President Trump said Wednesday.

In a barrage of tweets, the president called the alleged incident a scandal and witch hunt, later criticizing former FBI Director James Comey.

Comey then tweeted back: "Facts matter. The FBI’s use of Confidential Human Sources (the actual term) is tightly regulated and essential to protecting the country. Attacks on the FBI and lying about its work will do lasting damage to our country. How will Republicans explain this to their grandchildren?"

Many Democrats on Capitol Hill are echoing Comey’s concerns, while Republicans in large part have been backing the president. On Tuesday, several House Republicans even filed a resolution calling for a second special counsel to investigate what the FBI may have been doing speaking with members inside Trump’s presidential campaign.

“It will give authority to get to the bottom of these issues that [have] been brushed aside where justice has turned her head,” said Rep. Jody Hice, R-Ga.

“To think this could happen in one of our two major political parties during a campaign upsets me greatly. It should upset anybody whether they’re conservative like me or even a liberal Democrat,” said Rep. Chuck Fleischmann, R-Tenn.

Democrats are now warning of long-term repercussions.

“It’s beyond the pale in terms of appropriate presidential behavior respecting the rule of law,” said Rep. David Price, D-N.C.

“Little by little and sometimes, not so little, we're seeing an erosion of the independence of the Justice Department. That is gravely concerning," said Intelligence Committee ranking member Rep. Adam Schiff, D-Calif.

With a Thursday meeting now set for high-ranking DOJ officials to share highly classified information on this matter, Rep. Devin Nunes, R-Calif., chairman of the House Intelligence Committee, and Rep. Trey Gowdy, R-S.C., chairman of the House Oversight Committee, all sides seem to be preparing for a long fight ahead.
